If two beings at Super Saiyan 4 levels fuse, they STAY at Super Saiyan 4. This is not a basic math question where we ask "what is 4 + 4". There is no Super Saiyan 8. You, sir, have taken one too many blows to the head to think that.

Let's take this simply: Frieza was defeated by Goku just as he developed the first rank of Super Saiyan... Cell was defeated by Gohan once he released his rage in one burst to become a Super Saiyan 2... and during the fight with Majin Buu's final "kid" form, it took Goku all the power from his Super Saiyan 3 form AND a wish from the new dragon Porunga to restore his power back to maximum to defeat Kid Buu (but this was of course back when SS3 was the maximum).

In an "SS4 Fusion vs DBZ Villians" fight, based on power level alone, a fused Super Saiyan 4 has a better chance of winning this fight. Then again, if we throw abilities into this fight, Kid Buu may actually get the upper hand.

Like talking to a brick wall, this is... in order to fuse properly, three things need to be done:

1) The two beings must be of equal bodily stature; 2) they must perform the Fusion Dance to perfection; and most importantly 3) their power levels must be identical during the dance.

Their power does not immediately increase the moment they fuse; granted, the fused being is several times stronger than either of the two beings in the first place, but for the sake of fidelity... THERE IS NO SUPER SAIYAN 8. There never was, there is not now, and there never will be.

I take back my previous statement... even a brick wall has more sense than you do, it seems. For the last time... there is no such thing as "Super Saiyan 8". By posting that link, you proved all three of the points I made. And did you bother to look at the before-and-after? Gogeta's body after the fusion is identical to Goku and Vegeta's SS4 bodies... therefore Gogeta is also at the level of Super Saiyan 4... that's right, FOUR.

Stop arguing. I'm not going to lower myself to your level of idiocy any longer. I've put in my two cents, but apparently that skull of yours is sound-proof and won't let any proper sense in. The sooner you accept the fact that you're wrong, the better.

" god ur a bitch if they were the same whats th point of fusing and how did they woop whats his face so easy lest go by ur rules and chang the fit goku and vaget in ss 4 VS freza,cell,final buu?? "

1 Stop the name calling both of you! respect each other! consider this the first warning.2 They did it to become a stronger Super Saiyan 4 just like they did when they became Super Saiyan Vegito to fight off Super Buu
